PROBLEM TO BE SOLVED: To reduce a shock and improve fuel consumption, in the case of deceleration by brake operation when an engine is fuel cut controlled. SOLUTION: During fuel cut control (step S102), in a deceleration condition of the prescribed or more (step S104), further with decision of a battery not having a full charge amount, an intake/exhaust valve is normally opened (step S110), and simultaneously with this opening, a generator is regeneratively controlled. In this way, inside a cylinder communicates with an intake/exhaust pipe through a passage of the intake/exhaust valve, because of not compressing gas only by inside the cylinder, friction is reduced. |
